Title: Pellet bonding apparatus
Inventor: ARIGA MAKOTO
IPC: H01L21/52
Filed: 1983-07-13
Abstract: PURPOSE:To make it possible to perform an automatic inspection after the pellet bonding by providing means for determining whether the bonding conditions are good or not in accordance with picture recognition after the pellet bonding. CONSTITUTION:An IC package on which a pellet 8 has been bonded is fed along a guide rail 2 and halts at an inspection position. Thereupon, position information on the pellet 8 is delivered to a control unit 18 through a sensor 25 and an optical system 24 and positioning is then effected. The positions of four corners of the pellet 8 are computed. The sensor 25 catches the image of the pellet 8 and its vicinity and the resultant image signal is converted into a digital signal by means of a recognition unit 11. According to this image, the inspecting operation is automatically conducted as to a leakage shortage of molten metal of the pellet 8 and whether any flaw of the pellet 8 is produced or not.

IPC: C21B5/00
Filed: 1984-06-19
Abstract: PURPOSE:To economize on energy of a blast furnace by classifying undersize sintered ore to pulverous powder and small lumps on the basis of prescribed grain sizes, blowing the pulverous powder of the sintered ore through a blast tuyere into the blast furnace and charging the small lumps of the sintered ore together with oversize sintered ore into the furnace from the top thereof. CONSTITUTION:The sintered ore produced by a sintering machine enters a main sieve 2 from a sintering tank 1 and is classified to the sintered ore having >=5mm. grain size and the sintered ore smaller than said size. The sintered ore lumped at >=5mm. is put into a main hopper 3 and the undersize sintered ore below 5mm. enters a auxiliary sieve 6. The small lump sintered ore screened by the sieve 6 and having 2-5mm. grain size is charged into the main hopper 3 and is then charged together with the large lump sintered ore to the top part of the blast furnace 4. The pulverous sintered ore having <2mm. grain size screened by the sieve 6 is stored in a tank 7 and is blown by each prescribed amt. via an air feed pipe into the furnace through the nozzle 10 of the tuyere 9. The undersize sintered ore which is heretofore used for recycling is effectively utilized and therefore energy is economized.

Title: Actuating switch for passive belt device of vehicle
Inventor: ARAKI EIJI
IPC: E05B81/64
Filed: 1986-05-31
Abstract: PURPOSE:To prevent the occurrence of contact failure and improper operation due to the vibration of a contact point during running by providing a movable contact point brush turning following a switch knob and a fixed contact point plate in contact with said brush. CONSTITUTION:When the door of a vehicle has been closed and a striker part 21 has entered a guide groove 28, a latch part 22 turns and a hooking claw 35 first catches a half-open door hooking part 31. Then, a cam part 26 comes in contact with a switch knob 2 at the intermediate point of each hooking position with the half-open door hooking part 31 and a hull-close door hooking part 32. Subsequent hereto, the cam part 26 pushes the switch knob 2 and the displacement of the switch knob 2 causes the turn of a link 3 or the primary contact point 4a of a brush 4 for a movable contact point, and said point 4a comes in contact with a late 6 for a fixed contact point, thereby causing the connection of the plate 6 to a plate 10 for the movable contact point. As a result, the normal and reverse rotation of a driving motor can be changed over in a passive belt device.

Title: Engine driven constant frequency electric power generating set
Inventor: KANBARA HIDEKAZU
IPC: H02P9/06
Filed: 1987-05-23
Abstract: PURPOSE:To reduce the capacity of a variable speed rotary machine, by employing a cycloconverter type variable speed motor generator as the variable speed rotary machine. CONSTITUTION:When the number of rotation of a variable speed motor generator 10 is nullified, the number of rotation of a synchronous generator 12 becomes proportional to the number of rotation of an engine 1. When the number of rotation of the engine 1 is reduced, the variable speed motor generator 10 is operated as a variable speed motor and the speed of a sun gear 6 is increased. On the contrary, when the number of rotation of the engine 1 is increased, the variable speed motor generator 10 is rotated into a direction reverse to a case when it is operated at a variable speed motor and the speed of the sun gear 6 is reduced. According to this method, the number of rotation of the synchronous generator 12 may be kept in constant.

Title: Open type rotary electric machine
Inventor: YOSHIZAKI MASANOBU
IPC: H02K5/20
Filed: 1981-08-14
Abstract: PURPOSE:To offset drip-proof property and protective capability while removing oscillatory sounds due to electromagnetic oscillation by mounting an air guide plate with an air ventilating hole by the inner diameter side and outer diameter side of the air ventilating hole while being fixed to an end bracket. CONSTITUTION:When an end bracket 3 with a suction hole 10 is set up at the end section of a housing 1, an air guide plate 8 is mounted inside the end bracket 3. An air ventilating hole 8c is formed to the air guide plate 8 while the guide plate is fixed to the end bracket 3 by the inner diameter side 8b and outer diameter side 8a of the air ventilating hole 8c. Accordingly, oscillatory sounds are reduced because the drip-proof property and the protective capability are compensated while the rigidity of mounting sections is increased even when the suction hole 10 is enlarged.

Title: Controller for program shutter
Inventor: KONO TAKANORI
IPC: G03B9/24
Filed: 1991-04-30
Abstract: PURPOSE:To improve the cotrol accuracy at the time of high brightness of a program shutter by shortening the closing delay time to bring the point of the time for triggering for AE near to a pinhole position. CONSTITUTION:An opening/closing lever 1 closes a shutter vane 11 when its cam follower 1a is turned left by a cam edge 3c of a cam ring 3. The distance at which the opening/closing lever 1 turns right corresponds to the aperture value of the shutter vane 11. Objective field brightness is previously measured and the cam ring 3 moves precedently up to the point P0, P1, P2 where its cam edge 3c corresponds to desired aperture diameter values. The cam ring 3 drives the opening/closing lever 1 in the closing direction from the point P0, P1, P2 where its cam edge 3c corresponds to desired aperture diameter values when an AE timer 24 generates an exposure end signal and, therefore, the delay time is shorted by as much as the time corresponding to the precedent moving quantity of the cam ring 3 and the trigger point of a photoreflector 14 in brought near to the pinhole in correspondence thereto. The time table of the AE timer 24 is shifted in correspondence to the precedent moving quantity of the cam ring 3 corresponding to the brightness.

IPC: F01L1/344
Filed: 1988-05-26
Abstract: PURPOSE:To simplify the structure and reduce the cost by mounting a passive element which is made displaceable at a specified angle in the direction of rotation on a driving element in a valve operating device, and rotates the passive element by the expanding motion of a centrifugal weight which is attached to the driving element by a shaft. CONSTITUTION:In a device where a cam shaft 3 sequentially rotates with the rotation of a crank shaft through a timing chain engaged with a cam sprocket 4, and a valve is opened and closed by a cam 6, a pair of centrifugal weights 13 are shafted 14 in the opposite position on the side face of a driving element 12 which also serves as a cam sprocket 4. When the centrifugal force expanded the centrifugal weights 13 outward by the increased rotation of the driving element 12 overcoming a spring 18, claws 21 at the top of the centrifugal weights 13 disengage from the clamping concave parts 22 on a passing element 16 which is coupled with the cam shaft 3, thus, the passive element 16 is displaced up to the extent of a specified angle through the engagement of a peaking 19 on the passive element 16 and a gradient groove 20, causing a delay in the valve timing.
